Quick Answer
Acne is a common chronic skin condition characterized by clogged pores, inflammation, and breakouts affecting the face, back, and chest. It is suitable for teens and adults experiencing active acne or residual post-acne marks. Treatment works by targeting excess sebum, bacteria, and inflammation through a combination of medical-grade approaches tailored to skin type and severity. At ID Cosmetic Clinic in Markham and Toronto, acne treatment is personally performed by Dr. Dan Xu, M.D., with most patients undergoing a series of sessions spaced two to four weeks apart over several months.

What is acne? And why is it more than just “teenage breakouts”?
acne (Acne Vulgaris · ICD-10 L70.0) Is a type ofChronic inflammatory pilosebaceous unita condition involving four interconnected mechanisms: excess sebum production, abnormal follicular keratinization, Cutibacterium acnes (C. acnes) proliferation, and immune-mediated inflammation. It is not”inadequate cleansing”, Is a type ofa skin condition requiring medical management.
5 Commonly Misunderstood Facts About Acne
Not just a teenage problem — adult acne is increasingly common
25–45 the incidence of adult acne has risen significantly over the past decade,Especially cystic jaw-line acne in Asian women, Closely linked to hormonal fluctuations, stress, and compromised skin barrier — the treatment approach is entirely different from adolescent acne.
Acne is not a cleanliness issue — over-cleansing can actually make it worse
The root cause of acne isSebaceous gland dysfunction and abnormal keratinization, is not”not washing the face thoroughly”. Washing your face more than 3 times a day or using harsh cleansers disrupts the skin barrier,triggering more severe inflammation.
Post-acne marks ≠ acne scars — these are two entirely different concerns
Red post-acne marks (PIE) represent vascular dilation; brown marks (PIH) represent pigmentation; atrophic acne scars represent a loss of dermal tissue.All three require entirely different treatment approaches, Should not be combined.
“Squeezing breakouts is the leading cause of acne scarring
Squeezing inflammatory lesions by hand or with tools drives inflammation deeper into the dermis, disrupting collagen architecture and leaving permanent depressed scars.Every physician will tell you not to squeeze acne — and they mean it.
The #1 residual concern in Asian skin is PIH
Fitzpatrick IV–V Even after inflammation is controlled, the skinPost-inflammatory hyperpigmentation can persist for 6–24 months. This is why acne treatment in Asian skin must simultaneously address”Control active inflammation + prevent PIH + fade existing PIH”Three core lines.
Acne classification (by lesion type)
- non-inflammatory: Open comedones (blackheads) + closed comedones (whiteheads)
- inflammatory: Papules, pustules, nodules, and cysts
- Acne conglobata: Confluent nodules and cysts · High risk of scarring
- post-acne scarring: PIE Red marks (PIE) / brown marks (PIH) / icepick / boxcar / rolling acne scars
3 common acne patterns
T Predominantly in the T-zone (common during adolescence)
Dense comedones on the forehead, nose, and chin · Driven by androgens and excess sebum production · Responds well to topical retinoids.
Jaw cystic acne (adult females)
Breakouts that worsen predictably along the jawline or flare before menstruation are associated with PCOS or hormonal imbalance and typically do not respond to topical therapy alone.
Confluent cheek involvement (high scarring risk)
Deep bilateral cheek inflammation with nodule coalescence · Requires oral antibiotics + isotretinoin assessment · Early intervention is essential to prevent scarring.
The 5 Root Causes of Acne · Why Do Breakouts Keep Coming Back?
Acne ismultifactorial overlapoutcomes. Understanding your personal triggers is essential to breaking the cycle of clearing and relapsing.
Excess sebum production
Androgens stimulate excess sebum production, which combines with dead skin cells to clog follicle openings.Males + adolescents + women with PCOSsebum production is significantly higher.
Abnormal follicular keratinization (Hyperkeratinization)
Keratin buildup at the follicular infundibulum forms a microcomedone — the precursor lesion underlying all visible acne.Precursor lesion.
Cutibacterium acnes (C. acnes) proliferation
Anaerobic bacteria proliferate within blocked follicles, breaking down sebum into free fatty acids and triggering an immune response — resulting in inflammatory lesions.
Hormonal imbalance
Excess androgens, PCOS, menstrual cycle fluctuations, changes in contraceptive use, and elevated cortisol from stress can all significantly influence acne activity.
Inflammation + skin barrier + lifestyle
High-glycemic diet, whey protein, stress, sleep deprivation, over-cleansing, and skincare products with comedogenic ingredients (heavy oils, certain silicones) are all known triggers for recurring breakouts.
Acne vs. Rosacea / Folliculitis / Perioral Dermatitis / Seborrheic Dermatitis
Not every red papule on the face is acne — these conditions may look similar butTreatment approaches may be completely different, Misusing medication can worsen the condition.
vs Rosacea
| Are comedones present? | comedone-free (key differential) |
| location | Central face (nose, cheeks, chin) |
| Associated with | Persistent erythema + telangiectasia |
| Trigger | Heat, alcohol, spicy foods |
| Treatment plan | Metronidazole + PDL · BPO contraindicated |
vs Folliculitis
| pathogen | Staphylococcus aureus / Malassezia |
| morphology | Uniform papules and pustules |
| Itching | Often itchy (acne is typically not itchy) |
| location | Commonly affects the chest, back, and scalp |
| Treatment plan | Antibacterial cleanser + antifungal |
vs Perioral dermatitis
| location | Perioral · leaving a clear margin around the vermilion border |
| Trigger | Topical corticosteroids / fluoride toothpaste |
| morphology | Dense small papules and pustules |
| contraindications | Topical steroids are contraindicated |
| Treatment plan | Discontinue corticosteroids + oral doxycycline |
vs Seborrheic dermatitis
| morphology | Erythema + greasy yellowish crusting |
| location | glabellar area / nasal ala / scalp |
| Itching | Often accompanied by itching |
| pathogen | Malassezia-related |
| Treatment plan | Ketoconazole + anti-inflammatory skincare |
Why is PIH prevention the central challenge in treating acne in Asian skin?
For Caucasian patients, acne treatment success is measured primarily by inflammation control. For Asian patients (Fitzpatrick III–V),What truly lingers is not the acne itself, but the brown marks it leaves behind. This is the defining difference in the ID Cosmetic Clinic acne protocol.
1. 3 Key Characteristics of Acne in Asian Patients
- The inflammation itself is often milder, but residual PIH tends to be more persistent
- Jawline cystic acneProportionally more prevalent in adult Asian women than in Caucasian women
- more sensitive to irritation, Starting with standard BPO 5% or high-concentration retinoids frequently causes barrier disruption
2. PIH is the true concern for Asian patients
In Caucasian patients, post-acne red marks (PIE) typically resolve on their own within 3–6 months.Asian patients commonly develop brown post-acne marks (PIH) after breakouts resolve, Post-inflammatory hyperpigmentation can persist for 6–24 months or longer, particularly in Fitzpatrick IV–V skin types. This is why Asian acne protocols must“anti-inflammatory”+”pigmentation control”dual-track approach.
3. “Less is More”the same principles apply
Standard starting doses tolerated by Caucasian patients — such as BPO 5% and Tretinoin 0.1% — are often too strong for Asian skin. Dr. Xu begins withBPO 2.5% · Adapalene 0.1%Start gradually to allow the skin an adaptation period,a gradual, incremental processoften yields better results and less PIH than aggressive treatment from the start.
Fitzpatrick Graded risk assessment × Dr. Xu’s acne protocol
| Fitzpatrick | skin tone | PIH Risk | Dr. Xu’s protocol |
|---|---|---|---|
| II–III | fair / lighter skin tone | Low | Start with standard benzoyl peroxide (BPO) + Retinoid |
| III fade Asian | beige | Medium | Start at low concentration + early Cyspera for PIH prevention |
| IV typical Asian | millet-yellow | High | BPO 2.5% + Adapalene 0.1% starting point + Cyspera |
| V Deeper Asian / South Asian | Light brown | very high | Ultra-gentle initiation + early AviClear intervention + long-term Cyspera |
Many of my Asian patients tell me”The breakouts are gone, but brown marks have lingered on the skin for 3 years”. This is because the previous treatment focused solely on active inflammation without concurrently managing PIH risk. My acne protocol, from the very first consultation,making “No post-inflammatory marks over the next 24 months”Included as a treatment goal, Rather than simply chasing”today the breakout clears”. — Dr. Dan Xu, M.D., CCFP
Combination Acne Treatment Protocol (Medication + Device + Restoration)
There is no single “best treatment” — only the combination that is right for you. Dr. Xu designs a personalized protocol based on your acne severity, hormonal factors, and the presence of post-inflammatory hyperpigmentation (PIH) or residual scarring, drawing from the options below.
Topical Retinoid (Adapalene / Tretinoin) Cornerstone
Regulating keratinization, clearing microcomedones, and preventing new breakouts — the cornerstone of nearly every acne treatment protocol.Foundational medications. For Asian skin, begin with Adapalene 0.1% on alternate days and gradually build tolerance.
- Results typically emerge after 8–12 weeks
- teratogenicity · contraindicated during pregnancy
- Must be paired with moisturizer + SPF 50+
AviClear® 1726nm Acne laser treatment First-line non-pharmaceutical option
Health Canada–licensedSelective sebaceous gland laser, 1726nm Wavelength-targeted precision delivery to the sebaceous glands reduces sebum production at the source, minimizing comedones and inflammation — suitable forUnable or unwilling to take oral isotretinoinclients.
- 3 sessions, once every 4 weeks
- Minimal downtime · Makeup permitted after treatment
- Fitzpatrick I–V safety
- Results may last 1–2 years
Oral antibiotics (Doxycycline / Minocycline) Short-term
Used forModerate-to-severe inflammatory acne. 8–12 Short treatment cycles combined with topical medications help prevent the antibiotic resistance that can develop with prolonged monotherapy.
Oral Isotretinoin (Isotretinoin / Accutane)
Severe nodular-cystic / treatment-resistant acneGold standard. Requires close monitoring of liver and kidney function, lipid levels, and pregnancy status throughout a 6–9 month course. Dr. Xu will assess your suitability and coordinate referral or co-management as needed.
Hormonal regulation (adult females)
spironolactone (spironolactone) Anti-androgen therapy · first-line choice for jawline cystic acne;Short-acting oral contraceptivesHormonal cycle regulation · Requires co-assessment with gynecology. Clients with PCOS must have a full six-panel hormone workup.
Acne Scar Repair (Subcision / Bellafill / CO₂ Laser)
Inflammation fully controlled 6 More than several months— only then should acne scar revision be considered. Subcision is used for rolling scars, Bellafill for boxcar scars, and Fractional CO₂ Laser to stimulate collagen remodeling. Asian skin requiresLow energy, multiple sessionsto prevent pigmentation.
Post-acne mark management (PIE / PIH) Carried out concurrently
PIE Red mark: PDL 595nm pulsed dye laser, vitamin C serum, and PicoSure FOCUS.PIH Brown mark: Cyspera Cysteamine, PicoSure Pro® 755nm low-fluence treatment, and strict SPF 50+ sun protection.
Sample combination protocols (by patient profile)
| Patient profile | recommended protocol |
|---|---|
| Adolescent · T-zone comedones predominant | Adapalene 0.1% + BPO 2.5% + barrier restoration |
| Inflammatory · Moderate IGA 2–3 | Oral doxycycline 8 weeks + Retinoid + AviClear × 3 |
| Adult female · jaw cysts | Spironolactone + gynecological co-management + intralesional injections + Retinoid |
| Conglobate type · high scarring risk | Isotretinoin assessment + AviClear combination + subsequent acne scar revision |
| Post-acne PIH + superficial acne scars | Cyspera + PicoSure Pro × 4 + Microneedling RF |
How Does Dr. Xu Build a Comprehensive Acne Plan? (6-Step Process)
The complexity of acne treatment lies in the simultaneous presence of three overlapping phases — active inflammation, post-inflammatory hyperpigmentation (PIH), and acne scarring — none of which can be addressed in isolation.
Severity grading + lesion classification + phased treatment
- IGA Grading (Investigator’s Global Assessment) Grade 0–4
- Lesion count: Comedones / Papules / Pustules / Nodules & Cysts
- phased: Active phase / residual phase / scarring phase
- distribution pattern: T jawline / cheeks / chest and back
- Fitzpatrick classification + Medical history + medication history
Hormonal assessment (essential for adult female patients)
Jawline breakouts + premenstrual flares + hirsutism / irregular periods → referral to endocrinology or gynecology for a hormonal panel and PCOS screening. Spironolactone should not be initiated without confirmed hormonal involvement.
Assessing PIH and scarring risk
Three-dimensional assessment: Fitzpatrick phototype + history of lesion manipulation + current depth of inflammation.Any one high-risk factor → Proactively introducing Cyspera + AviClear without waiting for all inflammation to resolve before beginning pigmentation management.
Designing a 12-week treatment timeline
Acne treatment takes time and cannot be rushed — full treatment timeline:
[Weeks 0–2]Topical retinoid adaptation phase + barrier restoration
[Week 4]Session 1: AviClear (moderate to severe acne) + follow-up assessment
[Week 8]2nd AviClear session + topical regimen adjustment
[Week 12]3rd AviClear session + inflammation control assessment
[Weeks 16–24]Residual PIH / PIE Treatment (PSP / PDL / Cyspera)
[6 months later]Inflammation stabilized → assess timing for acne scar treatment
[long-term]Topical Retinoid maintenance + seasonal follow-up
Dynamic protocol adjustment at every follow-up
- Photo comparisonConsistent lighting + consistent angle to quantify lesions
- Assess tolerance: Barrier integrity, irritant response, and stinging sensitivity
- Fine-tune topical regimen: concentration, frequency, and combination
- Review of systemic medications: Liver and kidney function, lipid panel, hormones
- Lifestyle assessment: Diet, sleep, stress, and skincare products
Post-treatment residual management (the most critical phase after active treatment)
Acne under control ≠ end of treatment. Residual phase protocol:
- Long-term topical Retinoid maintenance (2–3 times per week)
- Cyspera + SPF 50+ Prevent worsening of PIH
- Seasonal follow-up (Seasonal sebum fluctuation in spring and autumn)
- Avoid comedogenic ingredients (education on reading skincare ingredient labels)
- Acne scar assessment window (after 6 months of stable inflammation control)
Acne is not “fixed in 3 laser sessions” — it isA medical journey that requires physician guidance over 6–12 months. Patients who come to ID Cosmetic Clinic for acne don’t receive a device package — they receive a complete, physician-led roadmap. — Dr. Dan Xu, M.D.
How soon will acne improve? How long does it take for post-acne marks to fade? How deep can acne scars be treated?
The most common pitfall in acne treatment is switching protocols after just 2 weeks of no visible results. Most topical medications and device-based treatments require 8–12 weeks before meaningful improvement appears. The tables below address the most frequently asked questions.
How soon will results be visible?
| phase | duration | visible changes |
|---|---|---|
| Topical Retinoid adjustment period | 2–4 weeks | may be transient”Active breakout phase”, is microcomedones being expelled |
| AviClear After the 1st session | 4–8 weeks | Reduced sebum production and fewer new breakouts |
| After completing the full AviClear × 3 series | 3–6 months | Significant reduction in inflammatory lesions |
| Residual PIH treatment | 6–12 months | Fading of brown marks, improved skin tone evenness |
| Acne scar repair (once inflammation is stabilized) | 6–18 months | gradual improvement in scar depth |
How many sessions are needed? (based on severity)
| type | recommended treatment | Maintenance period |
|---|---|---|
| Mild · Predominantly comedonal | Topical-only regimen + barrier repair | Long-term Retinoid maintenance |
| Moderate · Inflammatory | AviClear × 3 | Once yearly for maintenance |
| Severe · Nodular-Cystic | Isotretinoin assessment + AviClear | Regular follow-up after completing treatment |
| Residual post-acne PIH | PSP × 4–6 + Cyspera | SPF 50+ long-term |
| acne scar repair | Multimodal × 4–6 sessions + Filler | Once yearly for consolidation |
Recurrence rate (for reference)
| Maintenance status | 2 within-year recurrence rate |
|---|---|
| Regular Retinoid maintenance + seasonal follow-up + lifestyle modifications | 20–30% (Mild, recurring) |
| Medication discontinued + no maintenance plan | 50–70% |
| Uncontrolled hormonal factors (adult females) | 80%+ |

Acne treatment is not about “running a device” — it is about a physician charting a clinical roadmap.
The complexity of acne lies in the coexistence of three stages: active breakouts, post-inflammatory hyperpigmentation (PIH), and acne scarring. A unified plan under a licensed prescribing physician is essential to keep treatment on the right track.
About the cost of comprehensive acne treatment
The cost difference in acne treatment fundamentally reflects the depth of physician clinical judgment involved. What is similarly called”acne treatment”, Some clinics simply sell a fixed treatment session by session. A plan that truly resolves acne long-term, however, involves detailed medical history review, hormonal assessment, selection of topical and oral medications, device choice, PIH risk forecasting, and timing decisions for scar repair — most of which happen in a physician’s clinical judgment, not in a machine’s energy settings.
This is why the same treatment performed at different clinics can yield”acne treatment”Prices can vary several-fold. The difference isn’t the device itself — it’sWho is assessing, who is making clinical decisions, and how much hands-on expertise is involved throughout your treatment. Clients with complex cases, hormonal involvement, high PIH risk (Fitzpatrick IV–V), or a history of failed treatments generally benefit most from direct physician involvement. Clients in a stable maintenance phase may, following a physician assessment, proceed with treatments carried out by a trained aesthetic technician under an established protocol — offering a more cost-effective option.Treatment should be driven by clinical need, not by price. Following a Free 30-Minute Consultation, Dr. Xu will advise which level of involvement is most appropriate for your specific situation.

Who Is a Good Candidate for Acne Treatment?
Most healthy adults (18+) may be considered candidates following a consultation and clinical assessment.Not suitable:Pregnancy / breastfeeding / active serious systemic illness / active infection at the treatment site / known severe allergy history. Suitability is determined by Dr. Xu based on your medical history, anatomy, and goals during consultation.
How long do Acne & Breakouts treatment results last?
Results depend on the specific protocol, individual metabolism, and maintenance frequency. Dr. Xu will provide clear, realistic expectations based on your individual case at your consultation — We do not promise outcomes beyond what is medically realistic。
What are the side effects and risks of acne treatment?
All aesthetic procedures carry some risk. However, with Dr. Dan Xu (M.D., CCFP) overseeing every treatment, strict aseptic protocols, and personalized dosage and depth assessment, risks are kept within a reasonable, manageable range. Common mild reactions such as bruising or swelling typically resolve within 5–10 days. A detailed informed consent form covering all risks will be reviewed and signed at your consultation.
I'm already 30 — why am I still breaking out?
This isAdult acne,Incidence in Asian women continues to rise. Common triggers include: hormonal fluctuations (menstrual cycle / PCOS / discontinuation of oral contraceptives), chronic stress, over-layered skincare disrupting the barrier, and a high-sugar, high-dairy diet. Clinical presentation is typically deep inflammatory papules or nodules in a U-shaped jawline distribution. Treatment requiresEnergy-based inflammation control + barrier repair + coordinated internal medicine assessmentall three in parallel.
BBL Forever Clear How is it different from standard IPL?
Standard IPL primarily targets vessels and pigment, with limited efficacy on inflammatory acne. BBL Forever Clear is Sciton's purpose-built acne protocol,Three-wavelength protocol:420nm Blue light directly kills C. acnes, red light suppresses inflammatory mediators, and filtered wavelengths refine overall skin tone. Energy is dialed down 20–30% for Asian skin.
Why does over-exfoliating with acids make skin worse?
Three common mistakes: (1) Starting concentration too high —— Asian skin barrier tolerance is lower than Caucasian skin; (2) Treatments scheduled too frequently —— Multiple sessions per week or stacking with retinoids; (3) Continuing to peel on an already damaged barrier —— You should stop acid use for 2–4 weeks to restore the barrier first, then restart with a graded, low-concentration approach. Dr. Xu's protocol is always "repair the barrier before controlling acne" — never aggressive peeling from the outset.
Should I squeeze my pimples?
Never extract lesions yourself.Squeezing pushes inflammation deeper into the dermis, leading toAtrophic scars (icepick / boxcar)—— Treating acne scars is far more difficult and costly than treating the original acne. In-clinic "professional extraction" requires strict sterilization and microneedle-type tools, and is only appropriate for mature open comedones — never for inflammatory papules or pustules.
How long until I see results?
Depends on subtype:Comedonal type: 4–6 sessions((once every 3 weeks),Inflammatory type: 6–8 sessions((once every 2–3 weeks),Hormonal type: 6–10 sessions、Cystic + post-acne mark type: 10–15 sessions。The sebaceous gland cycle is 28 days, so any treatment requires at least 2–3 months to objectively assess response. Once acne stabilizes, you transition intolong-term maintenance phase every 6–12 weeks。
Can acne be treated during pregnancy or breastfeeding?
Most lasers and acids are contraindicated.Pregnancy and breastfeeding involve dramatic hormonal fluctuations, and any aggressive intervention increases PIH and irritation risk. Additionally, some topical agents (retinoids, high-concentration salicylic acid, benzoyl peroxide) carry safety concerns. We recommendPost-partum + after complete weaningbefore beginning systemic treatment. During this phase, start with gentle barrier-repair care and strict physical sun protection, co-managed with your family physician.
BBL Forever Clear How much per session? What about the full treatment course?
Acne treatment pricing varies significantly by subtype, severity, and required device combination. Simple comedonal acne may only require chemical peels + HydraFacial® maintenance; complex inflammatory / hormonal / cystic types require multi-line protocols combining BBL + skin booster + barrier management, with pricing structures reflecting the medical resources of physician-led care. Specific plans and fees are discussed during the free 30-minute consultation, alongside GAGS scoring and skin assessment.
Will my skin become more sensitive after treatment?
Not under a proper protocol. Dr. Xu's protocol'sThe core principle is: repair the skin barrier before any treatment,During treatment we use energy settings calibrated for Fitzpatrick III–V skin, followed immediately by cold compresses and barrier-repair skincare. If dryness or flaking lasts beyond 7 days, the protocol may be too aggressive or your home routine too irritating — book a follow-up to adjust rather than push through.
Can post-acne marks and acne scars be treated together?
MandatoryPhased。Phase 1: Control active acne and stabilize inflammation for at least 8 weeks. Phase 2: Treat red post-acne marks (PIE) with IPL, and darker PIH with low-energy Pico. Phase 3: Treat atrophic acne scars (icepick / boxcar) with Genius RF microneedling.Treating post-acne marks during the inflammatory phase actually worsens PIH,This is a common misconception.
I live in downtown Toronto / North York / Richmond Hill / Scarborough — is it worth the trip to Markham?
ID Cosmetic Clinic Located at 30 Gibson Dr., Markham — 30–40 minutes from downtown Toronto, 20–25 minutes from North York, 15–20 minutes from Richmond Hill / Vaughan, 20–30 minutes from Scarborough. At the Highway 7 + 404 / 407 interchange, with smooth evening return commutes.Acne is a chronic condition that requires long-term management —— Choosing a physician who understands Asian skin matters more than driving distance — acne scars from repeated mistreatment cost far more than the commute.
